cases, the alert is cleared even if the fault condition
exists, but the
ALERT output reasserts at the end of the
next conversion. The bits indicating the fault for the
OVERT interrupt output clear only on reading the Status
2 register even if the fault conditions still exist. Reading
the Status 2 register does not clear the
OVERT interrupt
output. To eliminate the fault condition, either the mea-
sured temperature must drop below the temperature
threshold minus the hysteresis value (4°C), or the trip
temperature must be set at least 4°C above the current
temperature.
Applications Information
Remote-Diode Selection
The MAX6699 directly measures the die temperature of
CPUs and other ICs that have on-chip temperature-
sensing diodes (see the Typical Application Circuit), or
it can measure the temperature of a discrete diode-
connected transistor.
Effect of Ideality Factor
The accuracy of the remote temperature measurements
depends on the ideality factor (n) of the remote diode
(actually a transistor). The MAX6699 is optimized for
n = 1.008. A thermal diode on the substrate of an IC is
normally a pnp with the base and emitter brought out
the collector (diode connection) grounded. DXP_ must
be connected to the anode (emitter), and DXN_ must
be connected to the cathode (base) of this pnp. If a
sense transistor with an ideality factor other than 1.008
is used, the output data is different from the data
obtained with the optimum ideality factor. Fortunately,
the difference is predictable. Assume a remote-diode
